28
Q

Sexually transmitted infection [STI]

A

Infection such as aids, chlamydia, or genital herpes that is normally passed from one person to another through sexual activity

29
Q

HPV (human papilloma virus)

A

Virus responsible for condition known as genital warts: transmitted by skin to skin contact

30
Q

GnRH

A

Gonadotropin releasing hormone: stimulates the release of FSH and LH

31
Q

FSH

A

Follicular stimulating hormone: since stimulates release of testosterone and estrogen

32
Q

LH

A

Lutenizing hormone

33
Q

Testosterone

A

Stimulate secondary sex characteristics in male: aids in spermatogenesis.

34
Q

Inhibin

A

Sends negative feedback to hypothalamus to stop secretion of GnRH

35
Q

Andropause

A

In men, I gradual decline in testosterone level beginning around age 40; symptoms include fatigue, depression, loss of muscle and bone mass, and drop in sperm production

36
Q

Menopause

A

Period in a woman’s life during which a decrease in estrogen and progesterone results in end of menstrual cycle is usually occurring around age 50

37
Q

Corpus luteum

A

Form from remaining follicle cells with an ovary: secretes estrogen and progesterone
-is pregnancy does not occur, corpus luteum degenerates

38
Q

Follicular phase

A
  • Development of follicle cells
  • first stage of ovarian cycle [part of the menstrual cycle]
  • Time during which increased levels of FSH them like the follicles to release increased quantities of estrogen in Sumter just ran into bloodstream, leading to the release of an egg from the follicle
39
Q

Luteal phase

A

– Second phase of ovarian cycle
– Beginning with ovulation; Jurin the stage, listen icing hormone stimulates the formation of the corpus luteum, with secretes progesterone and some estrogen, which stimulates the in the thickening of the endometrium for implantation of the embryo

40
Q

flow phase

A

Shedding of endometrium

41
Q

Hormone replacement therapy

A

Administration of low levels of estrogen and or progesterone alleviate symptoms of menopause in females

42
Q

Fertilization

A

Union of a sperm and egg cells to form a zygote

43
Q

Zygote

A

Result of egg and sperm union

44
Q

Cleavage

A

Rapid mitotic cell division with no cell growth

45
Q

Blastocyst

A

64 cell stage: hollow ball of cells

46
Q

Implantation

A

Process by which embryo becomes embedded in the endometrium

47
Q

HCG

A

Hormone only present during pregnancy

48
Q

Gastrulation

A

Change from that blastula to gastrula

>Gastrula: three germ layers are known as ectoderm, mesoderm, and endoderm

49
Q

Differentiation

A

The process and will become progressively more specialized as a result of gene regulation

50
Q

Allantois

A

In the amniotic egg, I’m membrane that encloses space where metabolic wastes collect.
>Extra embryonic membrane that forms the foundation for the umbilical cord

51
Q

Amnion

A

Extra embryonic membrane that forms a transparent sack that encloses and protects the embryo and fetus

52
Q

Chorion

A
  • surrounds the entire embryo along with the yolk and allantoic sack
  • membrane developed from the trophoblast in the blastocyst: develops into the fetal part of the placenta
53
Q

Yolk sac

A

Serves no nutritive function, but contributes to the formation of the digestive tract and produces the first blood cells and future eggs or sperm cells

54
Q

Placenta

A

Organ within the uterus that is rich and blood vessels; attaches the embryo or fetus to do uterine wall and facilitates metabolic exchange
>Allows the embryo to obtain nutrients directly from the mother

55
Q

Umbilical cord

A

Tube that connects the abdomen of fetus to the mothers placenta in the uterus, and through which nutrients are delivered and waste is expelled

56
Q

Parturition

A

The act or progress of giving birth

57
Q

Lactation

A

The secretion and formation of breastmilk for the mammary glands

58
Q

In vitro fertilization

A

Process in which eggs and sperm are brought together in a petri dish, where fertilization and cell division occurs. The developing embryo’s are then inserted into the uterus.

59
Q

Sterile

A

Used to describe men and women who are unable to have any children.

60
Q

Infertile

A

Being unsuccessful to become pregnant

61
Q

Tubule ligation

A

Cutting the oviducts and tying off the cut ends. this ensures that ovum never encounter sperm and never reaches the uterus [permanent birth control]

62
Q

Vasectomy

A

Ductus deferens are cut and tied. the man is still able to have an erection and ejaculate, but his semen does not contain any sperm.

63
Q

Stages in ovary

A
  1. Follicular phase (FSH)
  2. Ovulation (LH)
  3. Luteal phase (LH)
64
Q

Embryonic layers

A
  1. Ectoderm
  2. Mesoderm } produced by invagination
  3. Endoderm
65
Q

Layers: membranes around embryo

A
  1. chorion
  2. allantois
  3. amnion
66
Q

Gonads

A

Structures producing sex cells.

67
Q

Tubule ligation

A

-sterilization of the mother
-Prevents movement of ovum to ova duct
>”tying the tubes” (severing the Fallopian tube)

68
Q

Oral contraceptives (birth control pills)

A

Prevents ovulation
-contains man made hormones : estrogen and progestin.
> pill is taken daily to block the release of eggs from the ovaries.

69
Q

Condom

A
  • prevents pregnancy

- protects from HIV and STDS
